Is there a way to append information to the metadata of a feature class in model builder or in a python script. I want to create a script that copies data from SDE and archives it in a FileGDB but I need to add a date and information about the associated project phase to the metadata so that there is a record showing which stage in the project the data is referencing. I have a large number of feature classes that will have to be updated with the same information so I want to streamline this process. Any tips would be greatly appreciated.
At 10.1, the only way I know of that might work is to export the metadata, which will be XML, use python to parse and edit the xml, and then import it back in. Wish I could give more, but I haven't had a chance to mess around with it yet myself.
